Filter by:Ulcerative colitis (UC) is a relapsing chronic intestinal inflammation with no existing cure, that affects over 300 per 100.000 Canadians, the highest prevalence in the world. The standard drug therapies are expensive and potentially toxic, and mostly directed against the chronic inflammatory process. UC is the result of a dysbiosis between disease-inducing and protective intestinal bacteria in a genetically susceptible host. Non-digestible dietary carbohydrates (NDC) stimulate the growth of protective endogenous intestinal bacteria which ferment them into short-chain fatty acids (SCFA), some of the latter with natural anti-inflammatory properties, and are called prebiotics. The investigator was the first to report that oral intake of NDC, the dietary β-fructans inulin plus fructo-oligosaccharides (FOS), reduced colitis in a genetically-induced rat colitis model. Both inulin and FOS reduced colitis, each NDC modifying specific luminal microbiota. A small trial with the same mixture of NDC in patients with active UC relapsing on oral 5-aminosalicylic acid (5-ASA) showed a dose-dependent clinical response, confirming the translational potential of this NDC mixture. The investigators propose a randomized placebo-controlled trial to assess if inulin plus FOS can also prevent such relapses in UC patients with inactive disease on stable maintenance drugs. Primary hypothesis is that inulin plus FOS is effective adjunct therapy to standard drugs for maintaining clinical remission. The second hypothesis is that the colonic microflora and its metabolic function, altered by inulin plus FOS, or not, mediate protection or relapse in UC. The longitudinal design of this maintenance prevention study and by serially collecting colon biopsies, stool, serum and urine within the same patient before a relapse (inflammation) occurs, would enable to identify unique changes in the intestinal microbiota, their metabolic functions and also assess effects on host-immune response that are associated with remission or before a relapse occurs during treatment with beta-fructans, or not.
Vedolizumab (VDZ) is a humanized immunoglobulin G1 monoclonal antibody acting against α4β7 integrin which modulates lymphocyte trafficking in the gut. Results from the adult GEMINI-1 and GEMINI-2 trials demonstrated clinical efficacy in induction and maintenance of remission in both ulcerative colitis (UC) and Crohn's disease (CD), respectively. Recent real life cohorts in adults support the effectiveness of VDZ in inducing and maintaining remission, both in CD and UC. In pediatrics, there are very limited data on the use of VDZ besides two retrospective case series. Data on immunogenicity and therapeutic drug monitoring (TDM) of VDZ is conflicting in adults and practically non-existent in children. The investigators aim to prospectively explore the real life short and longer term outcomes of VDZ in pediatric IBD (including growth) and to develop a prediction model for treatment success based on VDZ trough levels and other clinical and laboratory variables.
A prospective case series investigating the efficacy and safety of dehydrated human amnion/chorion membrane (dHACM) in the treatment of patients with Stage II or III pressure ulcers
The aim of the study is to evaluate participant reported quality of life, safety, and overall performance with ACTICOAT in a clinical setting.
Patients with endoscopically diagnosed active duodenal ulcer disease were enrolled in a randomized, double-blind, parallel and dose-ranging trial. They were randomly assigned into three groups to be treated for up to four weeks and be seen at week 1, 2 and 4: three of ilaprazole, 5, 10 mg/day, and one of Rabeprazole 10 mg/day as positive control. The primary endpoint was the ulcer healing rate at week 4. Healing of ulcer was determined by its resolution from active to scarring stage. Symptoms relief was evaluated as secondary end points by using a graded score. Safety and tolerability were evaluated on basis of clinical assessments.
A Multicenter, Prospective, Randomized Controlled Comparative Parallel Study To determine the safety and effectiveness of EpiCord as compared to standard of care (SOC) therapy for the treatment of chronic, non-healing diabetic foot ulcers (DFUs)
The presence of pressure injuries has been considered a quality indicator of health care services and efforts has been made to develop guidelines to prevent this issue. Intensive care unit admissions (ICU) are recognized as risk factors to develop pressure injuries due to reduced mobility of critically ill patients and large number of devices and hard technologies that jeopardize preventive measures, such as, decubitus changes. There are not current definitive evidence about the superiority of any support surface to treat or prevent pressure injuries. The objective of the present study is to analyze if the use of viscoelastic support surface in vulnerable critically ill patients decreases the incidence of pressure injury compared with pyramidal foam support surface. Randomized clinical trial performed in an intensive care unit for adult patients in a philanthropic hospital. Inclusion criteria are patients admitted to ICU with Braden scale ≤ 14. Exclusion criteria are age under 18 years, less than 24 hours of ICU length of stay, contraindication of performing complete institutional preventive measures for support injuries, presence of support injuries at ICU admission or absence of informed consent. Randomization will be made by computerized generated numbers and patients will be allocated in two groups in a ratio of 1:1. All study patients will be cared for according to standard institutional preventive measures. The interventional group will be placed in an ICU bed with viscoelastic support surface and the control group in an ICU bed with pyramidal foam support surface. The main outcome evaluated will be the occurrence of type II pressure injury. Secondary outcomes are the time to the occurrence of pressure injury, length of ICU and hospital stay and 28 days mortality rate. Significance level will be 5%.
The purpose of this study is to evaluate the safety, tolerability, and efficacy of PF-06480605 in subjects with moderate to severe ulcerative colitis.
About 15% to 30% of patients with venous leg ulcers have a peripheral arterial disease (PAD) associated. The compression band is still a controversial issue in this context. It allows the reduction of venous hypertension and edema, but it could potentially degrade the arterial infusion of high levels of compression. The French High Authority for Health (HAS) defines mixed ulcers by IPS between 0.5 and 0.9. Investigators distinguish mixed ulcers blood predominance for IPS between 0.5 and 0.7; and mixed ulcers predominantly venous blood with moderate involvement for IPS values between 0.7 and 0.9. Several studies have shown that IPS> 0.8 allowed a high compression, between 30 and 40 mmHg. In the case of mixed ulcers with IPS between 0.6 and 0.8, the HAS recommends using a lighter compression, bit by elastic bands (exercising low power compression at rest) under medical supervision, informing the patient to remove the bandage if pain or aggravation. It is therefore necessary to adapt the compression therapy in case of venous ulcers associated with arterial disease by providing a lower compression 30 mmHg short stretch. For HAS, IPS <0.6 against indicates compression. A recent study showed that compression bit elastic bands could not only improve venous return, but it would also increase the distal arterial flow in a patient population with mixed ulcers. In this study, 25 patients had between IPS 0.5 and 0.8; or for certain patients below the threshold of 0.6 indicates that against a compression according to HAS. To our knowledge this is the only study that has examined the effect of compression on blood perfusion.
This trial will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of repeat dosing of UTTR1147A in participants with neuropathic diabetic foot ulcers that do not respond adequately to standard wound care. Participants across multiple sites will be assigned to one of five cohorts (Cohort A, B, C, D, and E) based on the eligibility criteria and randomized to receive subcutaneous (SC) injections of either UTTR1147A or placebo over 12 weeks in addition to standard wound care.
